To evaluate the expression 1/2 - (-3/4), we need to rewrite the expression to have a common denominator:

1/2 - (-3/4) = 2/4 - (-3/4)

Next, we can simplify the expression:

2/4 - (-3/4) = 2/4 + 3/4

Now, we can combine the numerators:

2/4 + 3/4 = (2+3)/4 = 5/4

Therefore, the correct answer is D) 5/4.

To find the temperature at 9:00 PM, we need to subtract 16.2 degrees from the initial temperature of 14°F:

14°F - 16.2°F = -2.2°F

Therefore, the temperature at 9:00 PM was -2.2°F.

So, the answer is A) -2.2°F.

Apologies for the mistake.

To simplify the expression 723 + (-514), you add the numbers:

723 + (-514) = 723 - 514 = 209

Therefore, the simplified expression is 209.

The correct answer choice would be C) 2 11/12.
Answered by GPT 3.5
Apologies for the confusion. Let's go through the simplification again:

To simplify 723 + (-514), we add the numbers. The negative sign before 514 means that we are subtracting 514 from 723.

723 + (-514) = 723 - 514 = 209

Therefore, the correct answer is 209.

None of the answer choices provided match the simplified expression.
